The pins holding the hard drives in Asus easyStore h340 are starting to break for me. The rubber is is old and snaps in half when handling. So I made 3D printed replacements.
The pin is keyed. Put it in and rotate 90° to lock it.
It should probable be printed with a flexible filament but I don't have any so I printed it in PLA.
